WALL CONSTRUCTION.

Toall whom it may concern:

Be it known that I, DENNIS a citizenof the United States, and a resident of New Brunswick, in the county of Middlesex and Stateof New Jersey, have 1nvented a new and Improved Wall Construction, of whichthe following is a full, clear, and exact description.

The invention relates to walls of houses and other structures formed of outer and inner sections; with an air space between them. 7 The object of the invention is to provide a ew and improved wall construction formed of hollow building blocks and arranged to securely tie the building blocksof the inner and outer wall sections together to. insure face thereof to building, the wall hangln s,

mer heat from penetrating the wall.

the formation of an exceedingly strong and durable wall. Another object is to prevent sweating of the wall and to prevent moisture from passing through the wall to the inner the detriment of the occuants of the urniture and the llke OOntH.lI18d 1Il t e rooms. Another object is to prevent cold frompenetrating the wall into the rooms of the building duringthe winter thus permitting of keeping the rooms comfortably warm on a moderate expenditure of fuel. Another. object is to keep the rooms cool during the summer time for preventing sum- Another obje ct is to permit the mason to quickly and accurately build the wall without requiring undue physicalexertion or high skill.

With these and other objects in view, the invention consists of certain novel" features of construction as hereinafter shown and described and then specifically pointed out in the claim.

Patented Feb. 3, 1920.

Application filed February 17, 1919. Serial No. 277,810.

The wall of a house or other structure ls formed of an inner section 10 andan outer section 11, the sections being spaced apart to provlde a dead air space 12 between the inner and outer wall. sections 10 and 11, as

plainly indicated in' Figs. 1 and 2. Each ofthe wall sections 10 and 11 is formed of courses of hollow building blocks 15 and 16, .of which the hollow buildin blocks 15 are alike in. size and shape an are 'usedfor the formation of the main portion of the corresponding wall section 10 or 11. 'ThB blocks 16 are similar to the blocks 15 exce tthat they are of less width and are main y used at the corners of the inner wall section 10, as lainly shown in Figs; 1 and 2. Each of the locks 15 is provided with at least one row of vertically dis osed openings 17 but' for thicker 'buildin locks another row of openings 18 is added as shown in Fig. 4,

and for still thicker blocks a third row of openlngs 19 is added as indicated in- Fig. 5. Each of the building blocks 16 is rovlded wlth only one vertical opening 20 ut it is expressly understood that I do not limit my- 7 self to the number of openings in any one of the building blocks '15 or 16.

In order. to tie the building blocks of a.

courseof building blocks in the inner and outer wall sections 10' and( 11 together the following arrangement is made: the building blocks 15 or 16 is provided on its inner face with vertically dis osed dovetail grooves 25 extendin from tiie top to the building block and the buildthe two wall sections 10 and wall sections 10 and 11 are engaged by. dove Each of tail tongues 26 formed on the sldes of a tie plate or-tile 27 extending across the air space .12. 7 It will be noticed that by the arran ement. described each pair of building bloc s inthe inner and outer wall sections 10 and 11 are securely tied together by the strong and durable wall construction without materially interfering with the dead air the wider bui ding blocks at the corner of the outer wall section 11, as will be readily um derstood by reference to Figs. 1 and 2. The

tie plate .27 thus providing an extremely) Q i aaaaaes .tie plates 27 of one course of building blocks are out of alinement with the tie plates in the preceding course, and although but one tie plate is necessary for a pear of buildin blocks, of the inner and outer sections 10 an 11 I do not limit myself to this arrangement as two or more tie plates mag be used for I each pair of building blocks, i

desired.

a In, practice, the building blocks in one course break joint with the building blocks in the preceding course and at the same time the grooves 25 of the building blocks in one course are out of register with the grooves 2-5 of the building blocks in the preceding of the tering grooves of a pair of buildin in one course rests at its lower en to be applied to the outer and inner faces of the walls. By reference to Fig. 1 it will be noticed that the grooves 30 of the building blocks in one course are out of register with the grooves 30'in the building blocks of the preceding course toinsure a proper adherence of.stucco or plaster.

It is understood that the blocks are laid 1n mortar or cement in the usual manner.

Although the building blocks in general referably made of hard burned clay orare simi ar material, for the inner section soft blocks known as nailin 11y and safely used wit out danger of moisblocks can be readture assin -.into' the room. The buildin P E g blocks of t e outer section of the Wall are preferably of hard burned clay but building blocks of terra cotta or building blocks having enameled or glazed faces may be used to heighten the architectural appear- .ance of the building;

Having thus described my invention, I claim as new and desire to secure by Letters Patent A'wall construction, comprising inner and outer wall sections spaced apart to provide a dead air space between them, each section being formed of hollow building blocks .provided at their inner faces with vertically disposed dovetail grooves, of" which the dovetail grooves ofthe blocks of the inner wall section are in register with the dovetail grooves in the blocks of the outer wall section,'and tying plates, one for each pair a of oppositely disposed. building blocks of the inner and outer sections, each tying plate terminating at its sides in dovetail tongues engaging a pair of register'n dovetail grooves in a pair of opposite buil ing blocks to tie each pair of building blocks together, the dovetail grooves in the building blocks of one course of the inner or outer wall section being out of vertical alinement with the dovetail grooves of the building .blocks in the next lower course of buildin blocks in the inner or outer wall sections w ereby portions of said blocks between said grooves underlie said grooves of the next upper course to provide seats forthe lower ends of the said tying plates to rest on, thus holding the tying plates in one course of building blocks against downward movement.
